Thanks for this link, Rich. It was very helpful in framing the whole concept of the Semantic Web, and what is might mean for the (near?) future. I think we are already starting to see different aspects of this, as sites are learning from the collective experience or analyzing the flowing of information into larger databases (the whole underpinning of Tim Berners-Lee's original vision of the web).
The question is -- how do we, as teachers, use this movement in the learning environment?
PS -- I also agree with Josie (below) that many people are still trying to wrap their heads around the idea of Web 2.0 and its impact and meaning.
You're lucky! Many people I work with haven't ever heard of web 2.0 and it comes as a bit of a shock to them to know there's "a new internet". The best way I've found of approaching it is to frame of the versions in terms of waves, similar to social movements. For example, First and Second Wave Feminism had a huge amount in common, some significant differences, and a lot of arguments over definitions, methods and aims in between. But they are approaches and activities on a continuum.
I think that most educators are clueless when it comes to Web 2.0. I think discussing Web 3.0 will simply confound the confusion. The purpose of a title is to help people understand something. For the non tech savvy educators Web 3.0 will not help. However, for those of us who have a clear understanding of Web 2.0 there's no problem in using the term Web 3.0. We just have to remember our audience. Just a thought!!
If Web 3.0 will be defined by the emergence of the semantic Web, I think this is a HUGE deal. For me Web 2.0 has meant the emergence of Identity on the Web -- i.e., content no longer is disembodied but is connected to living breathing people (e.g., social bookmarking, Ning :), blogs, etc.). Yet everything is still siloed. My presence here is this group is largely disconnected from my presence on Facebook, LinkedIn, my own blog, the Web site I run. For me, the promise of the semantic Web is to alllow people to trace out in an endless loop these links that the Web 2.0 technologies have allowed us to make between content and personality. For education, I think this means a deeper way of understanding and learning as you can trace all of the footsteps that connect people and ideas.
Actually, Jonathan and others, now that I think about it, I'm not sure I get it at all. What is the difference between web 2.0 and web 3.0? What does "semantic web" mean? Explain some more, if you're willing. It's intriguing.
Basically, yes. Who knows what will be invented tomorrow? My personal opinion is the next step for the web will have something to do with voice. Talking computers, computers that will interact, read a webpage, an email. Smarter computers.
web 3.0 is here in the form of a user centered system (see at www.4vision.com) that uses media feature extraction to automatically create sematically based personal digital media spaces wherein the user has the option to operate offline, online and connected to other network peers including those in the home peer network, and extended network communities such as social networks. The system supports many vertical market applications through the use of a high level abstraction based on a storytelling metaphor created through easy to use multimedia templates. For the education market deployment is in the form a personal learning environment application.
